Wild Predators Devour Bison Carcass in Yellowstone [WATCH]

This is one of the craziest videos I've ever seen. Ronan Donovan is a photographer for National Geographic. He also has some really good ideas. To get some incredible footage in Yellowstone, Ronan decided to drag the carcass of a bison into an open area and set a camera up in front of it. The result was definitely worth the struggle. Wolves, bald eagles, grizzlies, and coyotes all showed up to snack on the bison.
